p-toluenesulphoethylnitramide (m. p. 76°) is exclusively obtained. 
Strong sulphuric acid decomposes it with evolution of N30 and a 
nitro-p.-toluenesulphonic acid is formed, the barium salt of which 
- erystallises with 2 mols. of water. 
The dimethylamide of p.-toluenesulphonic acid yields with nitric 
acid of sp. gr. 1.48 dimethylamide melting at 57° while diethyl- 
amide yields with an acid of sp. gr. 1.5, amidst oxydation pheno- 
mena, a product which is liquid at first but solidifies after some 
time. When recrystallised from alcohol a product is obtained which 
melts at 76° and appears to be identical with the above mentioned 
nitramide nitrated in the nucleus, as obtained from the monoethyl 
compound. 
Nitric acid of sp. gr. 1.52 hag scarcely any oxydising action on 
the diethylamide, the product being again nitrated nitramide. After 
pouring the mixture into water and distilling a liquid product is 
obtained which sinks in water (ethyl nitrate). 
The properties of the said barium salt rendered it probable that 
the nitrogroup had occupied the ortho-position in regard to the 
CH; group. To make sure of this, I have endeavoured to prepare 
the nitrated nitramines by a method which showed with certainty 
the position of the nitrogroup in the nucleus. I first of all pre- 
pared a nitrotoluenesulphochloride by acting on nitrotoluene with 
HO-50, Cl; the product treated with ammonia yielded an amide 
melting at 140°, but the amount obtained left much to be desired. 
Even the action of P Cl; on the potassium salt of a sulphonic acid 
prepared by acting with fuming sulphuric acid on nitrotoluene 
(which yielded two isomers) did not produce the chloride in sufficient 
quantity to prepare the substituted amides. The action of ammonia 
produced two amides one of which melted at 141°. 
By acting on p.-toluenesulphochloride with absolute nitric acid 
a nitroderivative was obtained which could be recrystallised from 
petroleum ether when the temperature of the surroundings was low, 
and melted at 45°.*) With ammonia it yielded an amide melting 
at 143°. 
*) Fr. Réverpin and P. Crépreux BB. 34 (1901) 2993 state that they have obtained 
the same substance by nitrating p.-toluenesulphochloride with a mixture of nitric and 
sulphuric acids. [t melted at 36° but could not be recrystallised. They found the 
melting point of its amide to be 144°, this confirming the result obtained by ANNA 
Workow. In the literature at my disposal mention is only made of the wrong 
_ statements of Orro and GrÜBER who found 128°. I had already obtained my results 
when the paper of RÉVERDIN and CrÉPIEUX appeared.
